Papule and plaque A papule is a circumscribed, solid elevation of skin with no visible fluid, varying in area from a pinhead to 1 cm.James, William; Berger, Timothy; Elston, Dirk (2005) Andrews' Diseases of the Skin: Clinical Dermatology (10th ed.). Saunders. Page 15. .With regard to the quote "... varying in size from a pinhead to 1cm," depending on which text is referenced, some authors state the cutoff between a papule and a plaque as 0.5cm, not 1cm, while others state an entirely different measurement.

Clinical symptoms start with the formation of a red papule, which is characterized by a small raised swollen area of the skin. These can form on any area of the skin, with the arms, legs, arms and back most frequently affected. Patients typically do not report pain at this stage of infection. The papule enlarges with time, penetrates deep into the skin and develops a central opening, now classified as a furuncle.

B. henselae infection can appear up to ten days after exposure to the microbe. Symptoms start with a papule at the site the microbe enters, followed by lymphadenopathy, usually in the axillary node. Half of patients also get aches, nausea, abdominal pain, and malaise.Mazur-Melewska, Katarzyna, et al.

H. ducreyi enters skin through microabrasions incurred during sexual intercourse. The incubation period of H.ducreyi infection is 10 to 14 days after which there is progression of the disease. A local tissue reaction leads to development of erythomatous papule, which progresses to pustule in 4–7 days. It then undergoes central necrosis to ulcerate.

Pressing on a hive causes the skin to blanch distinguishing it from a bruise or papule. Hives can last for a few minutes or a few days, and vary from person to person. Also, a burning sensation occurs. A serious reaction is most likely to occur for patients where the hives occur with less than 3 minutes of exposure (during a cold test).

Pyogenic granuloma A pyogenic granuloma, is a small benign vascular tumor that primarily involves the skin (88.2%) and mucous membranes. Pyogenic granuloma appears as a red macule that grows rapidly, turns into a papule and eventually becomes pedunculated, being attached to a narrow stalk. The average diameter of these lesions is 6.5 mm. Although these lesions are small, they are often complicated by bleeding, crusting and ulceration.

EAH most commonly presents as a solitary papule or plaque on the extremities of children and are frequently congenital, although they can appear in adulthood as well. Rarely, multiple EAH lesions have been reported in a single patient, most often in an agminated pattern located on the extremities. A predisposition of EAH for facial and truncal involvement is not commonly seen. Some reports have demonstrated lesion predominance on the distal extremities.

In livestock, red imported ants mostly sting animals in regions with no hair, particularly around the ears, eyes, muzzle, the perineum and ventral portion of the abdomen. Newborn or young livestock can be blinded or killed when attacked by the ants. Healthy individuals are less likely to be attacked than weak or sick animals. Red papule and mild swelling occur, followed by vesicopustule with a red halo developing within 24 to 48 hours.

This test uses a small "button" that has four to six short needles coated with TB antigens (tuberculin), either an old tuberculin or a PPD-tuberculin. The needles are pressed into the skin (usually on the inner side of the forearm), forcing the antigens into the skin. The test is then read 48 to 72 hours later by measuring the size of the largest papule or induration. Indications are usually classified as positive, negative, or doubtful.

Intraoral dental sinus (also termed a parulis and commonly, a gumboil) is an oral lesion characterized by a soft erythematous papule (red spot) that develops on the alveolar process in association with a non-vital tooth and accompanying dental abscess. A parulis is made up of inflamed granulation tissue. Less commonly, dental infections drain onto the surface of the skin, forming a cutaneous sinus of dental origin. This condition is often resolved by endodontic treatment and does not have indication for antibiotic use.

Malakoplakia (from Greek Malako "soft" + Plako "plaque") is a rare inflammatory condition which makes its presence known as a papule, plaque or ulceration that usually affects the genitourinary tract. However, it may also be associated with other bodily organs. It was initially described in the early 20th century as soft yellowish plaques found on the mucosa of the urinary bladder. Microscopically it is characterized by the presence of foamy histiocytes(called von Hansemann cells) with basophilic inclusions called Michaelis–Gutmann bodies.

Pinta, the least severe of treponemal infections being limited to the skin, is thought to be transmitted by skin-to-skin contact (similar to bejel and yaws), and after an incubation period of two to three weeks, produces a raised papule, which enlarges and becomes hyperkeratotic (scaly/flaky). Lesions are usually present in the exposed surface of arms and legs. Local lymph nodes might be enlarged. Three to nine months later, further thickened and flat lesions (pintids) appear all over the body.

Cat-scratch disease is due to an infection by B. henselae and manifests as gradual regional lymph nodes enlargement (axilla, groin, neck) which may last 2–3 months or longer and a distal scratch and/or red-brown skin papule (not always seen at the time of the disease). The enlarged lymph node is painful and tender. The lymph nodes may suppurate, some patients may remain afebrile or asymptomatic. Other presentations include fever (particularly in children), Parinaud's oculoglandular syndrome, encephalopathy, and neuroretinitis.

Cherry hemangioma, H&E; stain Cherry angiomas are made up of clusters of capillaries at the surface of the skin, forming a small round dome ("papule"), which may be flat topped . They range in colour from bright red to purple. When they first develop, they may be only a tenth of a millimeter in diameter and almost flat, appearing as small red dots. However, they then usually grow to about one or two millimeters across, and sometimes to a centimeter or more in diameter .

Although it is not related to any pathological condition, hirsuties papillaris genitalis is occasionally mistaken for HPV warts. There are also home remedies for "curing" it, despite the fact that the papules are neither infectious nor detrimental to one's health and may have beneficial functions. Some of the "home remedies" found on the Internet and elsewhere use mild ointments or creams to soften the papules, but others are physically dangerous techniques for papule removal which can result in permanent genital mutilation. Rapini et al.

There are three type of tinea capitis, microsporosis, trichophytosis, and favus; these are based on the causative microorganism, and the nature of the symptoms. In microsporosis, the lesion is a small red papule around a hair shaft that later becomes scaly; eventually the hairs break off 1–3 mm above the scalp. This disease used to be caused primarily by Microsporum audouinii, but in Europe, M. canis is more frequently the causative fungus. The source of this fungus is typically sick cats and kittens; it may be spread through person to person contact, or by sharing contaminated brushes and combs.

There are several complications with the terminology: Acariasis is a term for a rash, caused by mites, sometimes with a papillae (pruritic dermatitis) or papule (papular urticaria), and usually accompanied by a hive (urticaria) and severe itching sensations. An example of such an infection is scabies or gamasoidosis. The closely related term, mange, is commonly used with domestic animals (pets) and also livestock and wild mammals, whenever hair-loss is involved. Sarcoptes and Demodex species are involved in mange, but both of these genera are also involved in human skin diseases (by convention only, not called mange).

D. medinensis causes dracunculiasis as a result of the emergence of the female worm, nonemergence of adult worms (usually the male), and secondary bacterial infections. As it emerges to the subcutaneous tissue, the female releases a toxic chemical that may result in nausea, rash at site, diarrhea, dizziness, localized edema, reddish papule, blister, and itching. Arthritis or paraplegia can result from a worm that fails to reach the skin and gets calcified in or along the joint or finds its way into the central nervous tissue. Aseptic abscesses and cystic swelling can also occur when worms rupture before emerging, causing an acute inflammatory response from the host's immune system.

Unlike in clinically healthy situations, parts of the sulcular epithelium can sometimes be seen in periodontally involved gingival tissue if air is blown into the periodontal pocket, exposing the newly denuded roots of the tooth. A periodontal pocket can become an infected space and may result in an abscess formation with a papule on the gingival surface. Incision and drainage of the abscess may be necessary, as well as systemic antibiotics; placement of local antimicrobial delivery systems within the periodontal pocket to reduce localized infections may also be considered. It is classified as supra bony and infra bony based on its depth in relation to alveolar bone.

In this context, incurability refers to the fact that once a host is infected with a herpesvirus, the virus will stay in the body in a latent state, and thus cause unapparent infection. To date, there is no antiviral drug or vaccine that can rid an infected body of a herpesvirus. Although herpesviruses remain in latent states within most infected hosts, opportunistic herpesvirus infections often affect individuals with immunocompromised systems. Such individuals will experience more severe symptoms than would usually be seen. For example immunocompromised individuals who are infected with HSV-1 would experience severe orolabial sores that could evolve from papule to vesicle, ulcer, and crust stages on the lip.
